When I originally bought my camper and for most of the time I owned it, the only back splash the stove really had was the three-inch tall piece of Formica that went with the counter top.
The rest of the wall was just the standard oak-wood grain paneling that made up all of the walls and cabinets in the camper.
This is okay, until you start full-timing in the camper and like to cook bacon or sausage, or anything that uses or produces some kind of grease. Even with a spatter screen, the natural vapor that comes from the cooking process gradually builds up on surfaces.
Trying to clean bacon grease build up out of porous wood paneling is a pain in the butt.
So, I was looking back one day through some of my photos I've collected of the Rociante, when I noticed a piece of regular sheet metal behind the stove in Steinbeck's camper.
That got me to thinking, and luck would have it, my original neighbors here at the park, the husband works at a sheet metal shop.
A little measurement and a bit of discussion later, and I now have a nice piece of heavy duty mirror polish stainless steel lining the wall behind my stove.
Clean up is a snap with a little bit of windex every now and then.
